Plant Production of Volatile Semiochemicals in Response to Insect‐Derived Elicitors

摘要: An increase in the release of volatile compounds by plants response to insect feeding is triggered interaction elicitors oral secretions herbivores with damaged plant tissues. This herbivore damage triggers de novo biosynthesis metabolites derived from several different biochemical pathways. Natural enemies use these semiochemicals locate their hosts. Although some are released storage immediately whenever cells or glands occurs, induced only synthesized and during light period. often results a delay between volatiles. Plants undamaged as well leaves. Thus, few leaves systemic volatiles entire plant. We propose that respond differently individual species at least part due composition come contact Specialist parasitoids can differentiate blends hosts those resulting non-host mechanical damage, thereby facilitating host location for parasitoid. Elicitors beet armyworm caterpillars have been identified synthesized.
